Blood Vessel Function Improved By Losing Belly Fat, Whether From A Low-Carb Or A Low-Fat Diet
Overweight people who shed pounds, especially belly fat, can improve the function of their blood vessels no matter whether they are on a low-carb or a low-fat diet, according to a study presented by Johns Hopkins researchers at an American Heart Association scientific meeting in San Diego that is focused on cardiovascular disease prevention. In the six-month weight-loss study, Hopkins researchers found that the more belly fat the participants lost, the better their arteries were able to expand when needed, allowing more blood to flow more freely.
Walking May Halve Genetic Influence On Obesity
Walking briskly for an hour a day can halve the tendency to obesity in people genetically predisposed to the condition, while a sedentary way of life that includes 4 hours or more of TV viewing a day can increase it by 50%, said researchers at an American Heart Association meeting in San Diego this week. Lead author Dr Qibin Qi, a post-doctoral research fellow in the Department of Nutrition at Harvard School of Public Health in Boston, Massachusetts, and colleagues, examined data on 7, 740 women and 4, 564 men taking part in two prospective studies: the Nurses' Health Study and Health Professionals Follow-up Study.
The Influence Of Genes On Obesity Can Be Halved By A Daily Brisk Walk
Watching too much TV can worsen your genetic tendency towards obesity, but you can cut the effect in half by walking briskly for an hour a day, researchers report at the American Heart Association's Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2012 Scientific Sessions. "While previous studies have looked at how physical activity affects genetic predispositions, this is the first study that directly looked at the effect of the sedentary behavior of television watching on the body mass index (BMI) of individuals with a genetic predisposition to obesity, " said Qibin Qi, Ph.
